[0019] A steel structure node horizontal calibration device comprises a clamp assembly 1, a steel structure 2, and a calibration rod 3. There are two steel structures 2. The connection end surfaces of the two steel structures 2 are sleeved with the clamp assembly 1. The clamp assembly 1 comprises a first clamp 4 and a second clamp 5. The top and bottom of the first clamp 4 and the second clamp 5 are provided with a first connecting piece 6 and a second connecting piece 7. A hanging ear 9 is provided in the middle of the outer surface of the first clamp 4 and the second clamp 5. The two hanging ears 9 are in the same horizontal plane. The calibration rod 3 is inserted into the inside of the two hanging ears 9. The longitudinal cross-section of the calibration rod 3 matches the internal opening surface of the hanging ear 9. A level bubble 10 is provided at the center of the front of the calibration rod 3, and a scale 11 is provided on the top of the calibration rod 3.

[0020] Furthermore, threaded holes 8 are provided at the centers of both sides of the first connecting member 6 and the second connecting member 7 , and fixing bolts are provided inside the threaded holes 8 . The two first connecting members 6 and the second connecting members 7 are connected by the fixing bolts.

[0021] Furthermore, fastening bolts 12 are provided on both sides of the connection between the calibration rod 3 and the two hanging ears 9 .

[0022] like Figure 3 As shown, threads are provided at both ends of the surface of the calibration rod 3, and the fixing bolts 12 here are nuts in the bolts. When the two ends of the calibration rod 3 are inserted into the hanging ear holes of the hanging ears 9, the fixing bolts 12 can be sleeved on the surface of the calibration rod 3, thereby facilitating the fixation of the calibration rod 3.

[0023] Working principle: The utility model includes two clamp assemblies, which are divided into a first clamp 4 and a second clamp 5.

There is a level bubble 10 in the middle of the calibration rod 3 to check and adjust the level of the steel rods at both ends. If the bubble is in the middle, it means that the rods at both ends are in a horizontal state. There is a scale with a spacing of 1mm in the middle of the calibration rod 3, which can be used to adjust the distance between the steel structures 2 to avoid excessive welds affecting the stability of the structure. After adjusting the level, the calibration rods 3 on both sides of the clamp are fastened by fastening bolts 12 to make the nodes more stable and convenient for welding. The utility model can improve the installation accuracy of the steel structure 2 and ensure the construction quality.
